Beta Versions

The Beta program for SharpCap 3.0 has ended. Please upgrade to the released version of SharpCap 3.0.

About SharpCap Beta

Beta versions of SharpCap have had less testing than usual and may contain unfinished or experimental features. If you choose to use a beta version of SharpCap, please test the cameras and functionality you intend to use before an observing session to avoid frustration and lost observing time. You can install a beta version of SharpCap without having to uninstall the previous release version, so it's easy to have both on the same machine and switch between them.

All beta versions have a built in time limit - they will only work up until a particular date (usually they have a life of a month or two). If your beta version runs out, check back at this page for an updated beta (or check the main downloads page for a new release).

NOTE: If your camera is not detected, you may need to install the SharpCap Pre-Requisites Installer. You only need to do this once, not for every new beta build.
